Bigger tube volme, heavier cone with a bit narrower shoulder will need more ejection punch in the shorter delay motors.

Do the new smallified ejection charges not at least equal what you'd get from a C6? I know I heard they were reduced from .5g to .3g, but I don't know what the equivalent would be in an Estes motor.
Makes me slightly worried about flying them on larger LPR models with 24mm mounts (where I was mainly interested in Q-Jet C, what with the demise of the C11.
